IM PROVEMENT IN GAS-REGULATORS.

Specification forming part of Letters Patent No. 181,875, dated September 5, 1876 application filed May 27, 1876.

To all whom it may concern Be it known that 1, ALEXANDER STRAUSZ, of the city of Washington, District of Columbia, have invented certain Improvements in Gas-Regulators, of which the following is a specification My invention consists in the improvement on a system of valves to be used in combination with a case or valve-chamber of peculiar construction, for the purpose of regulating the flow of gas to a burner or a series of burners connected thereto, to reduce the tension or on valve-seat F, Fig. 2, screwed into the valvechamber A. O is the upper valve; 1) and E, the spiral springs, and G the adjusting-nut, all of which are improvements on the instrument patented February 15, 1876, by J. P. Warner, of Baltimore, State of Maryland, and assigned to John R. Hall, of Philadelphia, State of Pennsylvania.

In operation, the drip or condensation of gas accumulates round the lower valve B, and on the valve-seat F, Fig. 2, thus preventing the valve B from lifting, and thereby obstructing the flow of gas into the chamber A. I improve the valve B by cutting slots for the purpose of letting the drip pass out of the chamber A, and consequently preventing the gumming of valve B on the valve-seat F, Fig. 2, and the obstruction to the flow of gas into the chamber A, which, in the old instrument, is caused by the gumming of valve B.

The upper valve 0 in the old instrument, as appears by practical experiments, never moves high enough to act as a further check to the flow of gas under an increased tension of the gas. I therefore place a spiral spring, D, un-

der the upper valve 0, and regulate the anthe same being acommon device; but in such arrangements the flow of gas fluctuates, and

does not make the saving as regular as with my improvement; so I make no claim to such combination.

1 claim- 1. The case A, the spiral springs D and E on spindle b, in combination with valves B and U, as described.

2. In a gas-regulator, the slotted valve B and springs D and E, all combined as and for the purpose as set forth.
